Why in News?

Recent flash floods in Rasuwa, Nepal, have shown the growing risk of climate-related disasters in South Asia. The disaster has caused a large number of deaths and left thousands of people missing. Recent reports put the death toll above 1,000, with around 4,000 people still missing. The event also damaged roads, bridges, and hydropower projects, making rescue work difficult.

1. Climate Injustice

Nepal produces only around 0.1% of global greenhouse gas emissions, but it faces serious climate-related risks. This shows an important problem. Countries that produce very little pollution can still suffer major losses because of climate change. This is known as climate injustice.

2. Vulnerable Communities

Climate disasters do not affect everyone equally. People with fewer resources often suffer more because they may not have enough money or support to recover.

Their vulnerability depends on:

  • Their income
  • Their type of work
  • Where they live
  • Access to basic facilities
  • Ability to recover after a disaster

Farmers, daily wage workers, and people living in high-risk areas are often more affected.

3. Case of Sri Lanka

Cyclone Ditwah (2025) badly affected Sri Lanka.

The Malaiyaha Tamil community, especially tea and rubber estate workers, was among the worst affected. Their long-standing social and economic problems made it harder for them to deal with the disaster.

Many families faced problems with:

  • Temporary shelters
  • Travel to work
  • Compensation
  • Permanent Housing

Watch: Climate Shocks in South Asia

Climate Shocks Are Becoming Successive

South Asia has faced many disasters in recent years.

These include:

  • 2018: Sri Lanka floods
  • 2022: Pakistan floods
  • Repeated floods in recent years: India
  • 2025: Sri Lankan cyclone
  • 2026: Nepal floods

The bigger concern is that people may face one disaster before they have fully recovered from the previous one. For example, a community may face drought, followed by floods, a cyclone, or a landslide. This makes recovery more difficult and increases the financial burden on poor families.

Why South Asia is Vulnerable?

South Asia is highly vulnerable to climate change because of its geography, large population, and economic conditions.

Ecological Interconnectedness

South Asia is closely connected through its rivers, mountains, monsoon system, and ecosystems. Many rivers and natural systems cross national borders. Because of this, a climate event in one country can also affect another country. For example, changes in river water levels or floods can have effects across borders.

Development Vulnerability

A large number of people in South Asia depend on:

  • Agriculture
  • Plantation work
  • Livestock
  • Daily wages

These workers often have limited savings and fewer resources. When disasters happen repeatedly, they may lose their homes, jobs, crops, or livestock. As a result, it becomes difficult for them to recover before the next disaster.

Lessons from Sri Lanka

The experience of Sri Lanka shows that weather conditions can change very quickly. During the 2018 Northern Province floods, authorities were reportedly giving drought relief only a few days before sudden floods.

This shows that a region can quickly move from one type of climate problem to another. So, disaster planning should not focus on only one type of disaster.

Need for Regional Cooperation

South Asian countries face similar climate problems, such as floods, droughts, cyclones, and landslides. However, these countries often deal with disasters on their own.

Present Gap

South Asian countries face many similar problems such as floods, cyclones, droughts, and landslides. However, countries often deal with these disasters separately. There is a need for countries to work together and prepare for climate risks in the long term.

What is Needed?

South Asian countries need better cooperation in areas such as:

  • Early-warning systems
  • Sharing climate and disaster data
  • Joint disaster response
  • River-basin management
  • Climate planning
  • Support for vulnerable communities

Better sharing of information can help countries prepare earlier and reduce losses.

Way Forward

Build Climate Resilience

The focus should not be only on helping people after a disaster. More attention should be given to preparing people before a disaster happens. Early-warning systems and evacuation plans should be improved so that people get enough time to move to safer places.

Protect Vulnerable Communities

Poor families and workers who depend on natural resources need more support. Special attention should be given to:

  • Poor households
  • Plantation workers
  • Farmers
  • Informal workers
  • People living in high-risk areas

They need better housing, basic services, and support to recover after disasters.

Regional Approach

South Asia should be treated as a connected region because climate and natural systems do not stop at national borders. Countries should share information and work together on disaster planning. A joint regional approach can help South Asian countries prepare better, respond faster, and reduce the impact of repeated climate disasters.
